Multiplatform project with Maven

I want to have multiplatform project that is written in Kotlin which is compiled to Java and JavaScript. The only requirement is to have it build under Maven. On official webpage there is information that Gradle is supported and no single word about maven. Did someone tried that and know if it is possible? Or there is strong dependency between multiplatform and Gradle? Is that even possible?

I have tried to find information about that but there is no information about that.
